Before this fix, resequencing would use values from _get_sequence_format_() run from an empty model.
This method result is influenced by the sequence_override_regex param of the move journal.
This means that if the journal of the moves that are resequenced has a sequence_override_regex param, it will be ignored in the wizard.
This fix run the _get_sequence_format_() method on the first move to take the journal into account.
Note that the wizard only allows resequencing moves from one same journal.
